> This is causing a bootstrap comparison failure in gcc/go/gogo.o.
I've had a look at this and the trigger is the
aarch64_use_constant_blocks_p change which appears to be causing a
bootstrap comparison failure because of differences to offsets when
built with debug and without debug. I don't think the problem is
specifically in the backend but this needs some careful
investigation. For now, in the interest of go bootstraps continuing on
trunk - I'm proposing a patch that partially rolls back the change in
aarch64_use_constant_blocks_p and am still looking into the issue but
it will take me some more time to get to the bottom of the issue.
Bootstrapped on aarch64-none-linux-gnu including (c,c++ and go) -
testing finished ok.

I was confused at first why tree-core.h was undefining DEF_BUILTIN_CHKP
before defining it, then undefining it again after including builtins.def.
This is because builtins.def provides a default definition of
DEF_BUILTIN_CHKP, but leaves it up to the caller to undefine it where
necessary. Similarly to the previous internal-fn.def patch, it seems
more obvious for builtins.def to #undef things unconditionally.
One argument might have been that keeping preprocessor stuff
out of the .def files makes it easier for non-cpp parsers. In practice
though we already have #ifs and multiline #defines, so single-line #undefs
should be easy in comparison.

In practice the definition of DEF_INTERNAL_FN is never reused after
including internal-fn.def, so we might as well #undef it there.
This becomes more obvious with a later patch that adds other
DEF_INTERNAL_* directives, such as DEF_INTERNAL_OPTAB_FN.
If the includer doesn't care about the information carried in
these new directives, it can simply leave the macro undefined
and internals.def will provide a definition that forwards to
DEF_INTERNAL_FN. It doesn't make much sense for includers to have
to #undef macros that are defined by internals.def and it seems overly
complicated to get internals.def to undef macros only in the cases
where it provided a definition. Instead I went with the approach of
#undeffing all the DEF_INTERNAL_* macros unconditionally.

This patch moves folds that deal with constant string arguments and
return a constant integer or floating-point value. For example, it
handles strcmp ("foo", "bar") but not strstr ("foobar", "bar"),
which wouldn't currently be accepted by the gimple folders.
The builtins.c folding for strlen (via c_strlen) is a bit more general
than what the fold-const-call.c code does (and more general than we need
for the gimple folders). I've therefore left it as-is, even though it
partially duplicates the new code.

builtins.def says that rint sets errno, but it looks like this might
be a mistake. C99 says that rint doesn't set errno and the builtins.c
expansion code doesn't try to keep errno up to date.
Perhaps this was because earlier versions of POSIX said that
rint sets errno on overflow:
http://pubs.opengroup.org/onlinepubs/009695399/functions/rintf.html
However, this is another instance of the observation that "rounding
functions could never overflow" (because anything using exponents
that large is already integral). The page above also says that
differences with C99 are unintentional and the ERANGE clause has
been removed from later versions of POSIX:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/rint.html
Also, the version of POSIX that lists ERANGE for rint does the same
for nearbyint:
http://pubs.opengroup.org/onlinepubs/009695399/functions/nearbyintf.html
and we already treat nearbyint as not setting errno. This too has been
clarified in later versions of POSIX:

In assign_parms_setup_block, the copy of args in PARALLELs from
entry_parm to stack_parm is deferred to the parm conversion insn seq,
but the copy from stack_parm to target_reg was inserted in the normal
copy seq, that is executed before the conversion insn seq. Oops.
We could do away with the need for an actual stack_parm in general,
which would have avoided the need for emitting the copy to target_reg
in the conversion seq, but at least on pa, due to the need for stack
to copy between SI and SF modes, it seems like using the reserved
stack slot is beneficial, so I put in logic to use a pre-reserved
stack slot when there is one, and emit the copy to target_reg in the
conversion seq if stack_parm was set up there.

Now that PR63304 is fixed and we have an option to address
any part of the memory using adrp / add or adrp / ldr instructions
it makes sense to switch out literal pools into their own
mergeable sections by default.
This would mean that by default we could now start getting
the benefits of constant sharing across the board, potentially
improving code size. The other advantage of doing so, for the
security conscious is that this prevents intermingling of literal
pools with code.
Wilco's kindly done some performance measurements and suggests that
there is not really a performance regression in doing this.
I've looked at the code size for SPEC2k6 today at -Ofast and
in general there is a good code size improvement as expected
by sharing said constants.
Tested on aarch64-none-elf with no regressions and bootstrapped
and regression tested in my tree for a number of days now.

* tree-ssa-threadupdate.c (valid_jump_thread_path): Also detect
cases where the loop latch edge is in the middle of an FSM
path.
* gcc.dg/tree-ssa/ssa-thread-11.c: Verify that we do not have
irreducible loops in the CFG.

The new routines operate on the built-in enum rather than on tree decls.
The idea is to extend this to handle internal functions too, with a
combined enum for both.
The patch also moves fold_fma too, with the same prototype. The long-term
plan is to replace FMA_EXPR with an internal function, for consistency
with the way that things like SQRT will be handled.
Tested on x86_64-linux-gnu, arm-linux-gnueabi and aarch64-linux-gnu.
gcc/
* builtins.h (fold_fma): Move to fold-const-call.h.
* builtins.c: Include fold-const-call.h.
(mathfn_built_in_2): New function, split out from...
(mathfn_built_in_1): ...here.
(do_real_to_int_conversion, fold_const_builtin_pow)
(fold_const_builtin_logb, fold_const_builtin_significand)
(fold_const_builtin_load_exponent, do_mpfr_arg1, do_mpfr_arg2)
(do_mpfr_arg3, do_mpfr_sincos, do_mpfr_bessel_n, do_mpc_arg1): Delete.
(fold_builtin_sincos): Use fold_const_call to handle constants.
(fold_builtin_1, fold_builtin_2, fold_builtin_3): Add explicit
checks for ERROR_MARK. Use fold_const_call to handle constant
folds for math functions.
(fold_fma): Move to fold-const-call.c.

directly.

This function is quite a puzzle; untangle it. No functional change.

* config/rs6000/rs6000.c (rs6000_reg_live_or_pic_offset_p): Rewrite.

This one for TARGET_TOC && TARGET_MINIMAL_TOC. Without it, r30 is not
saved in the prologue for functions that do not use r30, but the register
is set later in the prologue anyhow. This made all java tests fail.

* config/rs6000/rs6000.c (rs6000_reg_live_or_pic_offset_p): Use the
same condition for testing whether RS6000_PIC_OFFSET_TABLE_REGNUM is
live as for using it elsewhere, for TARGET_MINIMAL_TOC.

* tree-ssa-structalias.c (ipa_pta_execute): Add extra arg to call to
create_function_info_for. Dump constraints generated during
create_function_info_for. Move intra_create_variable_infos call and
function-return-values-escape bit to ...
(create_function_info_for): ... here, and merge
intra_create_variable_infos call with argument loop. Add and handle
nonlocal_p parameter.

* tree-ssa-structalias.c (create_function_info_for): Make sure prev_vi
updating is alap, and seperated from preceding code. Make sure
insert_vi_for_tree is seperated from surrounding code.
